Forget the typical cruise temptations of endless buffets and late-night snacks. A growing number of travelers are turning to the 'Low Carb Cruise' for an experience that combines a vacation with health and diet goals. This unique voyage caters to individuals who follow a ketogenic, or 'keto,' diet—a high-fat, moderate-protein, and very low-carbohydrate eating plan—or those interested in learning more about it.
The concept, created by Debbie Hubbs, who adopted a low-carb diet after the publication of Dr. Atkins' Diet Revolution in 1972, has grown significantly since its inception. Hubbs, who found success with low-carb eating for weight management, launched the first cruise in 2008 after discussions in an online forum. What began with just 30 participants has expanded to accommodate up to 360 passengers on recent sailings.
These cruises primarily take place on Royal Caribbean ships and are designed to provide an educational and supportive environment for attendees. The itinerary includes talks and sessions led by specialists and experts in the low-carb and metabolic health fields. Notable speakers have included Michelle Hall, a certified primal health coach specializing in women's fat loss and hormonal health, and Dr. Roberta Batista, a board-certified cardiologist focused on low-carb approaches for metabolic health and cardiovascular disease prevention. Amy Berger, a certified nutrition specialist, also participates, offering guidance on adopting a keto lifestyle.
Passengers have reported significant weight loss as a result of adopting the diet principles discussed on the cruise. While the cruise line itself does not provide specialized low-carb menus or food preparation, participants are educated on how to manage their dietary needs independently. The focus is on learning and personal application of the low-carb lifestyle.
The upcoming Low Carb Cruise in 2027 is scheduled to sail on Royal Caribbean's Navigator of the Seas, departing from Southern California and heading to the Mexican Riviera. In addition to the educational programming, passengers can enjoy the standard cruise amenities, such as entertainment, pools, and onboard attractions like a surf simulator and rock climbing wall. These activities are available to all passengers, with the low-carb group forming a smaller segment of the overall ship capacity.
